Official Reports of the Battle of Shiloh: No. 6. Col. Marcellus M. Crocker, 13th Iowa Infantry, Commanding the 1st Brigade, 1st Division, Army of the Tennessee

SIR: I have the honor to report the part taken by the First
Brigade of the First Division in the action of the 6th and 7th instant, after
4.30 o’clock p.m. of the 6th, at which time Col. A. M. Hare was wounded and
carried off the field and the command of the brigade devolved upon me. At this
time the Thirteenth Iowa Volunteers, Eighth and Eighteenth Illinois Volunteers
retired together, in obedience to command of Colonel Hare, and were rallied by
me, and formed after we had retired to position in front of the camp ground of
the Fourteenth Iowa Volunteers, and for the rest of the day and until the enemy
was repulsed they maintained that position under constant and galling fire from
the enemy’s artillery. The fire of his guns ceased at dark, and during the
night we remained under arms in that position.

On the morning of the 7th we were ordered to advance with
the division, at that time commanded by Colonel Tuttle, of the Second Iowa
Volunteer Infantry, and form a reserve to the advance of our forces that were
driving back the enemy and to support our batteries, which we did during the
day, most of the time exposed to the cannon and musketry of the enemy. Just
before the rout of the enemy the Eighteenth and Eighth Illinois Regiments were
ordered to charge upon and take a battery of two guns that had been greatly
annoying and damaging our forces. They advanced at a charge bayonets, took the
guns, killing nearly all the horses and men, and brought the guns off the
field. The enemy having retreated, and there being no further need of the
regiments under my command in the field, Colonel Tuttle directed me to return
with my regiments, the Eighth and Eighteenth Illinois and Thirteenth Iowa
Volunteers, together with the guns captured, to our encampment, which we had
left Sunday morning. This I did, arriving at the camp at 8 o’clock p.m. of
Monday. During this day our loss was small, the principal loss of the brigade
having occurred in the action on the 6th instant.

The entire loss of the brigade in this action during the two
days engaged is: Killed, 92; wounded, 467; missing, 18. A list of the killed,
wounded, and missing is herewith submitted.* We went into action with 2,414 men, and came
out of it on the evening of the second day with 1,795. Most of the officers and
men behaved with great gallantry and coolness.

Of Dresser’s battery and the Eleventh Iowa Volunteer
Infantry I can say nothing, excepting that I found what was left of them in
camp upon my return on the evening of the 7th, they having been separated from
the brigade during all the time that it was under my command.
